I wouldn't necessarily agree with this. Although Mike's cue isn't "100% level" with the table, he isn't "jacking up" either. Rather, Mike's giving himself enough clearance, that when he follows-through and drops his elbow, neither his hand or any part of the cue will crash down onto the interfering rail (the short side of the table he's standing at). When he's at his finish position, his cue is as level as it can be (which isn't "level" at all -- due to the cue having to clear the rail).
Any of the old-timer AZB'ers here rememeber "PeerLanda" (or "Peer")? Here's a video of his, that shows a local player with a monstrous draw shot -- easily two table lengths, exceeding that on occasion:

Granted, this is "let me see just how f'ing hard I can hit this, nevermind control" technique. But it does illustrate that monster draw shots are possible even without perfect technique (although Chris Capp [in the video] has textbook Lance Perkins pool technique).
